Compton Spectrometer and Imager Data

Data Directory: <https://spdf.gsfc.nasa.gov/pub/data/cosi/cosi2016/00readme.txt>  

The Compton Spectrometer and Imager, COSI, is a Compton telescope operating in the 0.2-5 MeV energy range and capable of imaging, spectroscopy and polarimetry of astrophysical sources. Such capabilities are made possible by COSI's twelve germanium cross-strip detectors, which provide for high efficiency, high resolution spectroscopy, and precise 3D positioning of photon interactions. This directory gathers the heliophysics data observed during the 2016 COSI balloon flight. In May 2016, COSI took flight from Wanaka, New Zealand, on a NASA super-pressure balloon. For 46 days, COSI floated at a nominal altitude of 33.5 km, continually telemetering science data in real-time. The payload made a safe landing in Peru, and the hard drives containing the full raw data set were recovered.
